Resonances and Complexity: From Stripes to Superstripes

The present issue of Journal of Superconductivity and Novel Magnetism collects the papers presented at the International Conference on “Quantum Phenomena in Complex Matter.” Superstripes 2010 held in Erice, Italy, from July 19 to 25, 2010, at the Ettore Majorana Foundation and Centre for Scientific Culture. In this preface, I discuss the scientific scenario of the search for the mechanism of the macroscopic quantum coherent phase at high temperature “superconductivity in complexity.”
